Ku'rahn of the Goldclaw Clan

As long as an equipped creature has first strike, Ku'rahn gets first strike. The same is true for lifelink, vigilance, trample, haste, double strike, indestructible, hexproof, shroud, unblockable, and reach.
{5}, {t}: Equipped creatures you control get +X/+X until end of turn, where X is Ku'rahn's power.
